A good gun and cheap, wouldn't we all want to find that.
A better question is what gun setup would I need to make it happen. I'm in college and don't have the time or money to waste on a gun that won't let me hit what I'm aiming at the first time I get the chance, which won't be often?
Shot gun-rifled barrel-scope-good ammo will get you started.
I have a Mossberg 500 12ga., rifled barrel, Bushnell Elite scope and use Remington Copper Solid or Winchester Partion Gold sabot slugs. When I put the hairs on something it's getting plugged. You have less than a minute to make a years worth of preparation count, a few bucks more to ensure it happens just makes sense. Also have a HR single shot 20ga. with a rifled barrel and Elite scope. Both can reach just about anything seen in the woods. Drilled a yotes head with the 12ga. @ 130 yrds.
Wanna waste time or kill deer? Not killing it is a huge waste of time and money.
Get the best you can get, it doesn't loose value.
